Patented Application Thi llllihtlfii .fiif i it foiijdispensing caps for bottles and especially for contalners for mucilage althoughit will be qu1te obvious ;;.-;;.that the principle involved adapts the invention equally well to the dispensing of other materials.

The primary object of the invention consists in the provision of a cap of rubber or ,;;.;the like of the type which employs a selfclosing slit and resides in. modifying prior constructions so that pressure of the cap on the paper or other surface to be supplied with mucilage automatically increases the ;-.,;prcssure within the container and forces the material outwardly through the dispensing slit.

vention will bc'apparent from the following ,;description when taken in connection with the accompanying drawing, in which,

- Figure l is a perspective view of the complete device.

Figure 2 is a vertical sectional view of the 7 package, the lower part of the bottle being shown in side elevation.

Figure 3 is a view of thedevice in dispensing position, parts-being shown in section.

Figure 4 is a fragmentary view of the device showing an extreme position of the dispensing head in operation, and

Figure 5 is an end view of the device as shown in Figure 4 looking in the direction of the arrows 55.

Referring to the drawing in more detail the numeral 1 indicates a container for the niucilage, here represented as a'bottle although other types of containers are equally well adapted to the invention.

The cap or closure for the bottle is preferably made of rubber and is provided with a neck engaging portion 2, formedof relatively heavy material and adapted to look under the annularshoulder 3 formed on the exterior of the bottle neck. Extending upwardly from the neck engaging portion 2 I of the cap is a cylindrical portion 4: also of rubber but having its walls made thin enough to be comparatively soft and flexible.

The outer end of the cylindrical portion Other objects and advantages of the ini P. r pheadingasil' .5 of the same thickness and flexibility as th wall 4:. Also it is to be noted that the joint between the cylindrical wall 4 and the end.

wall 5 is thickened as little as possible so as to maintain the desired flexibility in the dispensing portion of the cap.

A transverse slit 6 is formed in thewall. 5 to permit an extrusion of the contained fluid. This slit is automatically opened bypressure from within the container when the same is properly manipulated The upper end of the spreader 5 is preferably rounded as indicated-by numeral 7 so as to permit the use of the device in spaces which would .otherwise be inaccessible.

In operation, the spreading surface 5 of v the cap is applied to the paper being coated, in the manner indicated in Figure 3 or Figure 5 with a consequent distortion of the cylindrical portion 4:. This partial collapse of the dispensing portion of the cap reduces its capacity and thereby creates a pressure in the upper end of the inverted bottle which in turn forces the mucilage out through the slit 6 onto the surface being coated. In other words, the continued pressing of the device up and down on the surface being coated causes a pumping action which continues to' force the material through the slit 6. As the material is forced out onto the paper it is, of course,

spread out in the form of a band or ribbon by thespreader 5.v After the pressure is relieved within the container by discontini1-= ing-the above-mentioned action the slit 6 automatically closes and thus prevents deterioration of the mucilage remaining in the package. i

From the foregoing description takenin connection with the accompanying drawing it will be apparent to those skilledin the art that I have devised an exceedingly simple and inexpensive mucilagefpackage, that it may be readily manipulated to'extrude the required quantity of mucilage by mere pressure of the package on the surface to be coated, and that liability of contamieliminated.

Having fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. A rubber cap for dispensing mucilage or the like, comprising a portion adapted to surround and engage the neck of a bottle, a cylindrical portion of thin rubber communicati with said neck engaging portion but of su antially less diameter, said cylindrical portion including one relatively long vertical wall and a diametrically opposite and relatively short vertical wall, and a flat, inclined wall connecting the upper ends of the long and short walls of the cylindrical portion and closing the outer end thiireof, inclined wall provided with a s end thereof,

2. A rubber cap for dispensing mucilage or the like, comprising a portion adapted to surround and engage the neck of a bottle, a bulbous portion extending upwardly from the neck-engaging portion, acylindrical portion of thin rubber communicating with and extending upwardly from the bulbous portion, said cylindrical portion including one relatively long vertical wall and a diametrically op osite and relatively short vertical wall, and a Hat inclined wall connecting the upper ends of the long and short walls of the cylindrical portion and closin the outer said inclined wal provided with a slit.
